<P>PROBLEM TO BE SOLVED: To provide a keyboard device which is stably played, while obtaining key press feeling according to each sound region. <P>SOLUTION: The keyboard device 10 includes: a plurality of keys 11 which are pressed and operated; a key frame 12 which is disposed under the plurality of keys 11, and in which a support section 12c for supporting a rear end of the plurality of keys 11 so that each of front sections of the plurality of keys 11 may rock up and down; and a plurality of switch members 13 which is disposed on the key frame 12 according to each of the plurality of keys 11, and which becomes an ON state by being pressed by the plurality of keys 11 upon key pressing. The switch member 13 is disposed on the key frame 12 via a printed circuit board 15, and the printed circuit board 15 is tilted to the plurality of keys 11 so that an angle between each key 11 when the key 11 is rotated and it presses the switch member 13 to the ON state upon key pressing, and an opposite face of the printed circuit board 15, may become nearly a half or less of a rotation angle of each key 11. <P>COPYRIGHT: (C)2010,JPO&INPIT |
